External fixation is widely used in orthopaedic and trauma surgery. Infections around pin or wire sites, which are usually localised, non-invasive, and are easily managed, are common. Occasionally, more serious invasive complications such as necrotising fasciitis (NF) and toxic shock syndrome (TSS) may occur.

We retrospectively reviewed all patients who underwent external fixation between 1997 and 2012 in our limb lengthening and reconstruction programme. A total of eight patients (seven female and one male) with a mean age of 20 years (5 to 45) in which pin/wire track infections became limb- or life-threatening were identified. Of these, four were due to TSS and four to NF. Their management is described. A satisfactory outcome was obtained with early diagnosis and aggressive medical and surgical treatment.

Clinicians caring for patients who have external fixation and in whom infection has developed should be aware of the possibility of these more serious complications. Early diagnosis and aggressive treatment are required in order to obtain a satisfactory outcome.

Introduction: Idiopathic congenital talipes equinovarus (clubfoot) is a common complex deformity that occurs in approximately one or two per 1000 newborns. For many years, most surgeons considered it as a “surgical disease”. The long term results of the surgical release are disappointing, with increased foot pain, joints stiffness and muscle weakness.

It would appear that the most successful conservative treatment for clubfoot is the method developed in the late 1940s by Ponseti.

We recently reviewed the outcomes of treatment in Afula with the Ponseti method in our first 28 patients with minimum of five years follow-up.

Materials and Methods: In our study are included 28 patients (38 feet). 22 males and six females, 18 unilateral and ten bilateral cases, with idiopathic clubfoot. The average follow-up duration is of 6.5 years (range 5–8.5). The cases were evaluated using the 6-point clssfication system described by Pirani. Each foot was assigned a total score of 6 points or less, with higher scores indicating more severe deformity, 0 points indicate a normal foot.

Results: The average Pirani score at initial presentation was 5.5 (range 3–6). Only two feet out of 38 (7%), required complete surgical release, using the Turco method. The average number of casts applied was 7.5 (range, 5–13), and 35 of 38 (92%) feet required percutaneous Achilles tenotomy.

We used the Garceau classification to assess residual deformity. The average scoring was 3.6 points (range 2–4). Twelve feet out of 36 (33%) (excluding the 2 feet who underwent PMR), ended up with some residual supination, according to the Garceau classification, 11 feet rated 3 points each, and only one foot 2 points.

Only12 patients were defined as compliant with the use of the foot abduction brace. In seven out of 36 feet (18% of the feet, six patients) tibialis anterior transfer for residual supination was performed, only one of these patients was compliant with the use of the foot abduction brace. However, despite bad compliance with the use of the orthosis, eight out of 16 patients obtained good results.

An average of 13 degrees (range. 0–25) of dorsiflexion and 50 degrees (40–70) of plantarflexion was noticed in all 36 feet (again excluded the 2 post PMR feet), and very supple subtalar joints.

Conclusion: thirty-seven out of the 38 feet, at the latest follow-up, had an almost normal foot appearance.

Discussion: During the last nine years, the Ponseti technique has become the gold standard of treatment for clubfoot, with countless surgeons abandoning the surgical technique in favor of the Ponseti method.

Proper use of the foot abduction brace is essential. Those patients who underwent tibials anterior transfer, were non-compliant with the use of the brace. One of our patients whose parents refused to use the orthosis at all required complete open release with the Turco method.

Few patients may end up with good result despite bad comliance with the use of the brace. Since this is unpredictable, parents should be recommended to be fully commited as to the use of the brace.

Purpose: Correction of residual clubfoot deformities remains a great surgical challenge, and treatment failure is not uncommon. Open surgical reconstruction often leads to more scarring, risk of neurovascular injury, and a stiff foot. The Ilizarov external fixator allows for osseous realignment without open incisions. The Taylor spatial frame (TSF) is a relatively new external fixator that is capable of simultaneous six-axis deformity correction. Our method applies the Ponseti principles of clubfoot correction to a two-stage TSF correction (i.e., varus and internal rotation correction and then equinus correction). The Ponseti type 1 frame is programmed to correct varus and internal rotation first and then equinus. The Ponseti type 2 frame follows the same sequence as the type 1 frame but includes a final phase in which the foot ring is cut on two sides to allow separate correction of forefoot cavus and adductus. We present our initial multicenter experience with this Ponseti-inspired method.

Methods: During a five-year period, seventeen patients (22 feet) were treated for residual clubfoot deformities with the TSF. Nine patients had idiopathic clubfoot, five had arthrogryposis, one had myelomeningocele, one had developmental clubfoot, and one had clubfoot associated with fibular hemimelia. Eight boys and nine girls were treated. The average age was 6.5 years (age range, 1.75–15 years). Equinus, internal rotation, and varus were addressed in nine patients (Ponseti type 1 frame), equinus, internal rotation, and forefoot deformity (adduction and/or cavus) in six patients (Ponseti type 2 frame), and equinus only in two patients. All patients underwent correction with standard two-ring frames using a long bone program.

Results: All frames were removed after an average of 3.6 months (range, 3–8 months). One patient had under correction of residual equinus, but all others achieved full correction of deformities. Complications included superficial pin site infection in nine patients, talar subluxation in one patient, and subluxation of the first metatarsophalangeal joint in two patients. Infections were successfully treated with oral antibiotics. The one case of talar subluxation was reduced by the residual TSF program. The subluxated great toe was pinned in a separate surgery in two cases.

Conclusions: We believe that the Ponseti sequence of correction can be applied to older children with residual club-foot deformities even if they have previously undergone surgery. Our method with the TSF is a safe, accurate (computer-based), and effective treatment. It does not require open surgery, so the potential for scarring is minimized. It also allows for any subsequent treatments as needed.

Significance: The Ponseti-inspired method of residual club-foot deformity correction with the TSF is accurate and is a viable alternative to repeat open surgical procedures.

Background: The Ilizarov external fixation is considered to be a unique technique in limb surgery for mal-nonunion and limb deformities with or without length discrepancy. The theory suggests that the tension stress and the subsequent distraction osteogenesis, “opens a window” over hypervascularized- hypertrophic non-union for consolidation, and stimulates vascularization and osteogenesis in the avascular nonunion. Also, post traumatic bone deformities and axial deviations can be corrected by using special hinges incorporated in the device for uniplanar or multiplanar deformities. Recently, there are encouraging reports of high rate of consolidation using a non-bone grafting technique even in atrophic nonunions. However, the bifocal treatment is still preferable.

In our study we will review 28 patients suffering from mal- nonunion, whom were treated by an Ilizarov external fixation, and the results of the treatment concerning radiological alignment and consolidation rate.

Methods: Twenty-eight patients have been operated in our department during the last eight years due to mal-union (19 patients), mal- nonunion (3 patients) and non-union (6 patients) of fractures.

Malunions were treated either with acute or gradual correction of the deformity, following low energy osteotomy. For hypertrophic nonunion and mal-nonunion in general only distraction compression technique (mono-focal) was used. Atrophic and infected nonunion were treated with a bifocal technique (so-called bone transport), except for one case treated with monofocal technique only.

Results: The average age of the patients at operation was 31 years old (12–71), six female and 22 males. The average time in the device was 4 months (2–8) and average rate of consolidation was 3.6 mo. (2–7.5). All fractures and osteotomies healed thoroughly. Still, three cases of the mal unions remained suffering from residual deformity. Two patients had fracture of the regenerate after minimal trauma just after removal of device and treated with IMN. The most prevalent complication was pin tract infection, 24 out of 28 patients, all managed with P.O. antibiotics besides two patients who needed to be admitted for intravenous antibiotics. Two cases of lateral compartment muscle herniation of the leg appeared after fibular osteotomies, treated later by large fasciotomy.

Conclusions: The treatment of the different types of nonunion and malunion following fractures is a real challenge for the orthopedic surgeon. Many times the nonunions are the result of poor vascular supply to the involved limb. While the surgeon is facing old scars and poor nourishment of the entire limb, the Ilizarov external fixation, in most of the cases, enables us to deal with these difficult cases with minimal surgical exposure. In case of malunions, Ilizarov technique enables to achieve accurate angular correction of the deformities.
